The Context:

Reducing carbon emissions has become one of the main challenges in the transportation sector. The aviation industry is no exception and is also committing to a CSR (Corporate Social Responsibility) approach with a goal: to contribute to the climate cause. To achieve this, one solution being considered is to make airplanes lighter, particularly by reducing passive insulation in the fuselage. To contribute to this effort while maintaining passenger comfort, FACTEM, along with two other partners, is developing an electroacoustic solution as part of a project co-financed by Europe: the OASIS project.

The OASIS Project:

The OASIS project, Open Acoustic System for Individual Sound, is a compact active noise reduction system integrated into passenger seats, offering two main functions:

1. Reduce localized noise through active control without increasing mass, while providing a noise reduction performance of -10 dB.

2. Reproduce a localized audio source without causing discomfort to the surroundings.

After feasibility studies and tests conducted in the environment, FACTEM presented a first proof-of-concept demonstrator of its solution at its booth during the Paris Air Show last June.

Opportunities:

The solution developed within the OASIS project aims more broadly at reducing the mass of acoustic insulation and therefore addresses all types of transportation: air, rail, and road. The localized reproduction would also allow diversifying the rail offering by introducing new services such as a private isolated space for professional users.

Our partners and funders:

The OASIS project consortium consists of three entities: ARTEAC-LAB, the project leader, is a company based in Marseille whose core expertise lies in the engineering of electro-acoustic systems, particularly applied to the transportation sectors. The LMA (Laboratoire de Mécanique et d’Acoustique) is a Marseille-based laboratory specialized in human perception of sound. Finally, FACTEM complements the consortium by bringing its expertise in electroacoustic design and its industrial perspective for project implementation.

For this project, FACTEM is co-financed by the European Union.

Who are we?

FACTEM is a French company located in Bayeux, Normandy (14). It operates in various industry sectors and is organized around two business units: acoustics and industrial detection. FACTEM's ambition is to design and manufacture increasingly innovative products using new technologies to offer its customers high-performance and quality equipment. To achieve this ambitious goal, FACTEM invests more than 12% of its annual turnover in Research & Development to continuously accelerate its growth. FACTEM internally controls all stages, from design to manufacturing to after-sales service. Through its international development actions, FACTEM aims to have the quality of its products and expertise, 100% 'Made in France,' recognized."
